Now that 'The Walking Dead' season 3 has closed up shop, for better or for worse, AMC and their recent facelift are all about the style and panache of 'Mad Men,' premiering its sixth season this Sunday with "The Doorway." In advance of the premiere, AMC has released a number of photos from the two-hour event, which reveal the full extent of Pete Cambell's sideburns, as well as a few other plot points people are probably into as well. Get a look at 'Mad Men' season 6 inside!

'The Walking Dead' finale "Welcome to the Tombs" may have made you mad, but it's got nothing on Sunday's 'Mad Men' season 6 premiere "The Doorway." AMC's official press description tells us that Don spearheads a new campaign in Hawaii while Roger gets some unsettling news, and Betty takes in a houseguest, but know that the specter of Death will cast a large shadow on the premiere.

AMC has released a number of photos from the premiere that predictably see Don, Megan and the rest of Sterling-Cooper-Draper-Pryce living it up, apparently opening at Christmas time. The photos also highlight Pete's dastardly sideburns, and a devious smile on Sally Draper's face, but their new looks are nothing compared to what we'll see from Harry Crane this year.

Take a look at the 'Mad Men' season 6 premiere photos below, and tell us if you'll tune in for "The Doorway" on Sunday, April 7!
